We have recently received three very similar phishing/malware attack emails, one pretending to be from Google +, one from Skype, and one from Facebook.

They all have the similar subject line of 'You have delayed messages.

The emails are unsophisticated (the addresses and links in them are obviously not from who they say they are) but do use real logos.

They each have 'View messages' links which point to websites that have been hacked. Don't click these links - at best they will take you to a phishing site, at worst they will download viruses or other malware onto your computer.
